Ok, thank you Deanjo.

OpenSSL RSA 4096-bit test is a bit suspect!
These results should be expected as the OpenSSL that comes with OpenSolaris uses the Crypto Framework.

Solaris: 8 CPU, 32 cores. 2.6 GHz
Linux: 8 CPU, 32 cores. 2.8 GHz
Windows: same setup as Linux
See the official pdf benchmark from SAP website here.
The problem is utilization. Solaris is close to 100% utilization on all cores. Windows is down to 87% utilization on all cores. In other words: Windows doesnt scale to well. Nor does Linux. The cores are not fully pegged. Solaris cores are fully pegged so scales better: 25% faster than Linux, on slower hardware. 21% faster than Windows, on slower hw.
Such results shouldn't be expected, because Linux and *BSD also have this.

But SAP has validated and approved those benchmarks. The benchmarks are checked and certified by SAP. On the "SUN propaganda web page" there are links further to SAPs home page showing those certifications. I copy & paste those links for you, because you do not believe links on SUN web page. Here are those links, they are not on SUN web page anymore, those links are now free and "cleansed" from SUN propaganda:

We see that Linux only achieves 87% utilization on the cores. This shows that Linux does not handle many cores well, on a single machine.
Solaris certified SAP result on 32 cores, from SAP home page:
I understand that if SUN links to those white papers, you guys dismiss those white papers as "propaganda". But if SAP hosts those white papers, then it is not SUN propaganda anymore. Then it is maybe SAP propaganda.
Or, maybe SUN should not have pointed to those links. Instead SUN should have waited until you guys discovered them by yourself. If you discover that white paper by yourself, then you could not accuse them of being SUN propaganda. If SUN links, then that link is useless propaganda. The trick is that SUN must not link. But how will we discover that link, if no one points them out?
In hind sight, I should have pointed to those white papers on SAP web page myself. Then you guys could not have accused them of being SUN propaganda. Next time, I will not point to SUN web page (that points to the benchmark/white paper). Instead, I will point to the white paper/benchmark directly myself.

Oops, my bad. The CPUs are six core, not quad core. So all machines have 8 CPUs and 48 cores. Which is clearly stated if you closer read the white paper on SAP home page.
